SPECIFICATION forming part of Letters Patent No. 681,513, dated August 27, 1901.

Application filed February 6, 1901. Serial. Ilo. 46,177. (No model.)

To all whom it may concern: K

Be it known that I, FRANK A. RYTHER, a

,citizen of the United States, residing at Chicago,in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corn-Shockers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in-the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this 'specification. l

My invention relates to shock forming and hoisting devices for corn-harvesters and mayl In the drawings, Figure 1 is a perspective g view of my shock sustaining and lifting device, and Fig. 2 is a side elevation of the automatic tripping mechanism. Fig. 3 is a side elevation, partially in longitudinal section, of the post, the adjustable head, and the means for locking the arms in radial position. Fig. 4. is a plan view of the post and adjustable head shown in Fig. 3. Fig. 5 is a perspeetive View of a portion of one of the radial arms. Fig. 6 isa side elevation of one of the plates of the tripping-lever K shown in Figs.

l and 2. Fig-7 is a perspective vie.r of the looking-link J shown in elevation in Fig. 2.

A may be considered to be the circular table of a rotary corn-shocker. Upon it the shock is formed in the usual manner either by placing the stalks on4 by hand or by me# chanical means, as in the patents above referred to. Upon and at the center of this table is a plate having a strong sind o', which passes upward into the post B. This post for lightness and convenience only is made oi a square tube.

C is a crane situated upon any portion of the cornshocking machine, having the pulley c. i.

Upon the top of the post is the pulley D.

Wlen pulling` the rope o' by windlass or otherwise, the shock and the post around which the shook is formed will be lifted and by movement of the crane in the usual manner the'shock swung to one side of' the machine and dropped. A Y

-Upon the post is the adjustable head E, provided with ears, between which the arms e, e', e2, and e3 are pivoted. Each arm is provided with the short arm c4, which serves as a detent. The adjustable head E is secured to the post B by means of a pin e5, which is passed through it and through any of the holes b along the post. lThe pin and holes are provided as means for holding the radial arms any height from the table that may be required. In long corn they are placed higher than in short corn. Near the lower end of the post are thev radial arms f, f', f2, and f3, pivoted to the head F in preciselythe same manner as the longer arms are pivoted to the adjustable head E. These arms are practically counterparts of the arms shown in Fig. 5; but they are made shorter and slope downwardly until they touch the table. The purpose of these arms is to permit the trash that may have fallen from a previous shock when liftedto be moved on them by the pressure of the butts of the stalks for the new shock as they are forced toward the een ter of the table, and thusbe taken away from the table when the post is lifted.

Upon the post are the collars G, adapted to move freely. They have a {iange g, (shown in Fig. 3,) between which and the post the short ends of the radial arms are held. Turning now to Fig.` 3, the means for locking the arms to position will be readily understood. In full lines the flange g is seen to engage the short arm or detent e". If now the 4collar G is moved upward, as shown by dotted lines inFig. 8, the arm is set free and permitted to fall to its position parallel with the post, as shown in dotted lines. What is true of one of these arms is true of all, and it is equally true of the radial arms at the lower end of the post. The two collars G are con- IGD ' corn.

, 'of 4the device. l It is readily seen that if thev nected to the bar g by bolts or otherwise. Said collars and bar could be permanently as one piece but for the fact that it is desirpost be lifted from 4the table, swung to one side, and the trigger pulled the arms will fall under the weight of the shock and the shock will drop to the ground. This trigger may be pulled by any suitable devices; but

I'showmeaus` for making it operate automatically, whichwill now be described.

At the top of the post B, Fig. 2, is a stopsleeve H, having the collars h and h on either end. The trigger, part of which is the bar g', passes upward alongside the postB and is so turned that an eye g2, formed in it, loosely surrounds ythe stop-sleeve H. The pulley D is provided with a case d, and through it passes a pin which forms the axis of rotation of the pulley. This case d has arms or straps d' extending downwardly, one oneach side of the pulley, and united by a cross-bar at their lowerends. In a hole in this cross-bml l the stop-sleeve H is sustained, the collar h holding it in position. the stop-sleeve H the pin I passes upward and has formed in it an eye, which in its normal position is some little distance above the straps IJd is Athe locking-link J, which in its normal -position is in the position shown in Fig. 2. 'It will be readily seen that when in its normal yposition the weight of the post B, vwith all its'parts and the shock form ed thereon, is sustained bythe locking-link Jthrough the intermediacy of the pin I and the swivel I'.

My automatic means for tripping the trigger, referred to above, consists in mechanism for moving the parts of the tripping device, consisting of the lever K and the locking-link J, out of their normal and locked position, and thus allowing the post and the shock formed upon it to drop a short distance. The mechanism for permitting it to drop a short distance and the distanceit drops is shown in Fig. 2. I accomplish thisby releasing the locking-linkJfrom its normal position, (shown in Fig. 2 in full lines,) thereby allowing the pin I and the post B, with its trigger and the shock formed thereon, to drop such distance as provided by suitable proportioning of the parts of the tripping device above referred to. Before the post B andthe shock formed thereon has reached the limit of its downward 'lhrough a hole gin.

movement the eye g2 of the bar g ofthe trigger thus arrests the-downward movement of the trigger. The distance that the post B moves after the trigger has been stopped is sucientto raise the flange g above the short arms or detents e4. .This disengagement ofthe flange g with the short arms or detents e4 allows the Aarms e, e', e2, and esfand in a like manner the being received between them, forming the' This, however, is a mere' matter of convenience. The said lever is pro.

vided with'a hole to receive the pin k and the locking-link J with a hole to receive the pm, link7J i s pivoted to the pinI and by the pin k to the lever K. It 4will also be observed that the three pinsj, lo, and It 4are not in line and that the pin if.' in the movement of the parts passes beyond a line drawn through the centers of the other twothat is, passes the By means of the pin j the locking-A engages the collar h ofthev stop-sleeve H, and

dead-center so far that the locking-.link J one of the iianges of the pulley D are formed ratchet-teeth d2.

With the parts inthe position shown in Figs. l and 2 it may be assumed that thev shock has been formed and is readyto be lifted f rom the table. To accomplish this,the rope c' is drawn inthe direction indicated by the arrows by windlass or otherwise. AAs it moves the pulley 'D rotates and the pawl L harmlessly clicks in the ratchets. When the shock is fully raised and swung from the table and the rope permitted to move in the direction opposite that indicated by the arrow, the pawl engages the ratchets and, movingthe arm K on its axis lo, swings the'upper end ofthe locking-link J to a position to the right of' a linedrawn through` the pins j and la, as shown in Fig. v2, when the post and shock are permitted to fall the little distance provided. When this takes place, the locking-link J drops downward until it strikes the ange h of the stop-sleeve H, which arrests the descent of the post B, the descent of the trigger, as I have seen t to call it, having been Apreviously arrested by the eye g2 of thebar g' coming in contact with the collar h', as above described. The shock having thus been deposited upon the ground, the shockforming device is placed again .upon the revolving table A, the strong stud a roo IIO

passing into the post B. Until the weight of downward position, as shown in dotted lines in Fig. 2. lVhen now the postBV is replaced on the table and its Weight removed from the pin I, the Weight M, attached to the lever K on the opposite side'ot' the pivot Zt from the pawl L, moves the lever K upon its pivot Zr and brings the pawl L againinto action with the ratchet-teeth4 d2. It is evident, however, that a spring maybe supplied in lieu of the weight'M. p
